Great way to keep your crazy puppy busy.
Color: blue
This is our second automatic dog toy we’ve boughten. The first one was big and just had one movement with different speeds. This one is so much better. It’s smaller so it’s not so heavy, perfect for a puppy. It has a soft squeak, at first I was worried it was going to drive me nuts but I don’t even notice it. When it squeaks it moves one way then it starts moving another way without squeaking. Keeps my puppies attention. He likes to grab it and fling it back and forth where sometimes it hits him in the head, thankfully this one is smaller and lighter so it doesn’t hurt him. It’s great quality, seems like the material is going to last through lots of chewing. Would 100% buy again and recommend.
